I am a newbie in the Arduino World but have some knowledge on Electronics, programming (java, .net, linux and some scripting …)
Am trying to connect a Siemens A52 LCD to my arduino Uno, but am confusing and i need help, any help.
How to connect the LCD to my arduino
After some googling, i find pin wiring for the A52 LCD
Some articles says that the Siemens A52 lcd use the PCF8812 controller and that lcd must be drived by a2.9v
Q1: Can i use the arduino 3.3v pin for lcd vcc or should i add a voltage divider or some 317 regulator or separated power Supply (2 x AA 1.5v)
Q2: For other pins (clk, data, …) should use PWM pins? or any.
2- Software (libraries)
Q3: which LCD library should i use to get a correct display
Some topic like (http://forum.arduino.cc/index.php?topic=268044.0) use successufully the U8glib but with mirrored displaying.
Any other ?
Thank you for any help.
